Node.js Website Crawler Tutorials

Whether you are looking to obtain data from a website, track changes on the internet, or use a website API, website crawlers are a great way to get the data you need. While they have many components, crawlers fundamentally use a simple process: download the raw data, process and extract it, and, if desired, store the data in a file or database. There are many ways to do this, and many languages you can build your spider or crawler in.

Node.js is a server development environment that facilitates building applications in JavaScript, and that are called by webpages using JavaScript.
